DYNAMIC CONTRAST ENHANCED IMAGING BASED PERMEABILITY METRIC

机译:基于动态对比度增强的磁导率度量

摘要

A method includes determining a permeability metric of vascular tissue of interest based on a first time enhancement curve and second time enhancement curve corresponding to a first contrast material and a second contrast material flowing through the vascular tissue of interest and generating a signal indicative thereof. A computing system includes a time enhancement curve generator (114) that receives first dynamic contrast enhanced imaging data representing vascular tissue of interest and a first contrast material with weakly permeating particles and that receives second dynamic contrast enhanced imaging data representing the vascular tissue of interest and a second contrast material with strongly permeating particle and generates a first time enhancement curve for the first contrast material and a second time enhancement curve for the second contrast material and a permeability metric determiner (116) that determines a permeability metric for the vascular tissue of interest by determining an effective difference between the first a nd second time enhancement curves.
